Title: An improved method of and apparatus for separating gasolene from natural gas or hydrocarbon vapours
IPC: C10G5/04
Filed: 1923-10-18
Abstract: 224,688. Chadwick, J. W. Oct. 18, 1923. Oils, recovering.-Gasoline is separated from hydrocarbon vapours, natural gas, &c., by washing the vapours with a solvent, such as crude oil, distilling off the gasoline and returning the solvent for treatment of further vapours. The vapours are supplied by a pipe 2 to the lower end of a vertical chamber 1, packed with sheets 10 of expanded metal down which solvent flows from a pipe 6. Liquid entrained by the vapours is separated by a conical partition 11 having radial slots shaped to give the gas a whirling motion. The solvent passes from the base of the chamber through a pump 9, and a heat-exchanger 68, to a heating coil 20 discharging into a vessel 22 contained in a heating- chamber 23. The overflow from the vessel 22 passes into a counterweighted vessel 41 having a small drain-hole. When the vessel 41 is full it falls and through levers 42-48 opens a valve 29 supplying heating- agent to the burners 25, 26. When the flow of oil is stopped and the vessel 41 empties, it rises and closes the valve 29. The oil passes over inclined baffles 39 to the base of the chamber 23, from which it is returned by a pump 66 through the heat-exchanger 68 and a cooling-pipe 5 to the top of the column 1. The vapours from the chamber 23 pass through a dephlegmating tube 52 which returns the heavy fractions, and through a condenser 57. The temperature of the tube 52 is regulated by a thermostatic device at its upper end, which opens or closes a plate 55 covering the upper end of a surrounding tube 54 and regulating the circulation of air in this tube.

Title: Improvements in and relating to electric switches
IPC: H01H15/18
Filed: 1921-10-07
Abstract: 191,161. Hougardy, A. Oct. 7, 1921. Switches, quick-action. -In snap-action switches of the dead-centre type, an insulating disc 5 pivoted at 16 in a metal frame 17 carries peripheral contacts 1, 3 which are in electrical connection with the frame 17. The disc 5 has an eccentric pin 7 working in a segmental slot 14, a spring 6 being connected between this pin and a fixed point 8 on the frame 17. The switch-operating member is a sliding bar 10 terminating in push pieces 12, 13, the bar 10 having a central slot 10 through which projects a finger 9 attached to the disc 5. By depressing a push piece 12, 13 the disc moves angularly over the dead centre position, the spring 6 completing the motion with a snap action, lost motion provided by elongation of the slot 11 preventing shock on the operating member. At opposite extreme positions of the disc 5, when the pin 7 is at one end of the slot 14, one of the contacts 1, 3 engages a fixed insulated blade contact 2, 4, the switch being of the two-way type. By omitting one pair of the co-operating contacts, the switch is converted to the single-way type. An alternative form of lost motion between the operating and contact members, Fig. 5, consists in a finger 19 pivoted on a pin 20 in the disc 5 and sliding in a hole 21 in the operating rod 22. The switch mechanism may be contained in an insulating pear-shaped casing 18.

Title: Seat belt and locking means therefor
IPC: B60R22/347
Filed: 1965-06-23
Abstract: 1,068,404. Safety harness. J. G. FONTAINE. June 23, 1965 [July 23, 1964], No. 26522/65. Heading A3V. A safety belt-retracting device comprises a spring-loaded roller 13 normally locked against rotation in the wind-in or unwind direction by engagement of a pawl 18 with ratchet 17 on the roller shaft 14a. As shown, the pawl is disengaged from the ratchet against the action of springs 19 by means of a solenoid 25, the armature 24 of which is coupled to the pawl by a pin 20. The solenoid is energized from the vehicle battery by means of a push button (7) which is also connected to a heater coil (28) (Fig. 6, not shown) for heating and thus distorting a bimetallic strip 29. On energization of the solenoid causing withdrawal of the pawl, the pin 20 forces a contact (35) on a spring strip 32 against a contact 33 on the strip 29, thus maintaining the solenoid energized until heat distortion of the strip breaks the contact. The springs 19 then force the pawl back into engagement with the ratchet. In an alternative arrangement, Fig. 9 not shown, the pawl is disengaged from the ratchet by a vacuum or pressure fluid supplied by a bleed valve arranged to retract the piston and pawl rapidly and to retard the spring- assisted return movement. In either embodiment, the pawl control means may be reversed; the solenoid for instance being continuously energized, e.g. whilst the ignition switch is on, to maintain the pawl in engagement with the ratchet against the action of the springs.

Title: The control of apparatus subject to mechanical vibration
IPC: B06B3/00
Filed: 1951-11-13
Abstract: 695,770. Automatic vibration control systems. AEROFLO (PROPRIETARY), Ltd. Nov. 13, 1951 [Nov. 15, 1950], No. 26586/51. Class 38 (iv). [Also in Groups II, XIX and XXXVII] The amplitude of vibration of a motor-driven machine, such as an electric fan, is limited or regulated by a displaceable rod operated by contact with a part of the machine when the vibration is excessive. In the case of a machine which is intended to vibrate, such as a conveyer or screen, a second displaceable rod is operated when the vibration is of sub-normal amplitude, and the two rods operate jointly to correct the speed of the machine. Warning devices may also be operated when the vibration is abnormal. As shown in Fig. 1, a switch-actuating rod 14 is slidably supported in a tube 10 and its free end is fitted with an adjustable head 16 which is positioned close to a part 23 of a motor-driven machine. The opposite end of the tube 10 is secured by a lock-nut 13 to a bracket 11 fixed on a base 12. The other end of the rod 14 is attached to a lever 17 near its spring-pressed convex pivot 33, and a link 18 at the opposite end of the lever triggers a micro-switch associated with a movable contact bridge 19. When vibration is excessive, the head 16 is pressed by the machine 23 and the switch 19, 20 is closed, causing stoppage or reduction of speed of the motor driving the machine, and/or operation of a visual or audio warning device. When the invention is applied to vibrating machines, such as conveyers or screens, a second switch is provided, a head similar to the head 16 being spring- pressed against a vibrating part of the machine and arranged to close a switch when the vibration amplitude is subnormal. In Fig. 3, the two switches 20a, 20b are arranged to energize coils 28a, 28b, respectively, and these coils control a reversing switch 29 in the supply to a speed control motor 31, thereby raising or lowering the speed of the main motor 32 according as the vibration is below or above a desired normal amplitude.

Title: Process for the catalytic refining of mixtures of benzene hydrocarbons under pressure
IPC: C07C7/00
Filed: 1955-09-16
Abstract: In the hydrofining of mixtures of benzene hydrocarbons, especially crude benzol, in which the starting material is pretreated at a lower temperature, of at least 200 DEG  C., under lower pressure than during hydrofining to form polymerization products, the benzene hydrocarbons are distilled off from the polymerization products in a separating column by heating the mixture before it enters the column exclusively with waste heat from the hydrofining reaction.  Such waste heat may also be used in the preliminary polymerization treatment, and for heating the hydrocarbon vapours and the hydrogen or hydrogen-containing gas before or after they are mixed together to bring them to hydrofining temperature.  The heat necessary to start the reaction is supplied by passing the gases and vapours through a tube heater, which is cut out when the exothermic hydrofining reaction starts.

Abstract: 982,316. Knitting-machines. WILDT MEL -  LOR BROMLEY Ltd. July 19,1962 [July 25, 1961; April 12, 1962, Nos. 26833/61 and 34097/62. Heading D1C.  In a circular knitting machine of the cylinder and dial type selective shogging of needles in one bed is produced by the lateral deflection of each of said needles from one side to the opposite side of an adjacent needle in the other bed without relative turning movement of the beds to the circumferential extent of one complete needle space. In one modification (Fig. 1) spaced spin gears 8, 9 are provided in which teeth of the gear 8 are offset circumferentially with respect to the teeth on wheel 9. Rotation of the gears produces a deflection of the needle head which return to their original position when they have passed by the gears unless held by holding bits 12 in the verse 3b. The needles are reduced in thickness to facilitate the operation of the gears. The spun gear axle may be held on a bracket (not shown) which may be pivoted to allow the gears to move into an engagement position with the needles. In a further modification (Figs. 7 and 8) the needle tricks are offset with respect to the tricks 14a on the dial and the verge 15 is recessed at 16 and houses individually yieldable elements 16 with operable portions 17a which moves into a needle returning position when the needle is advanced and deflected. The operable portion 17a is uncovered by the sideways movement of the needle stem and it moves out to contact the adjacent side of the needle stem and hold it in the deflected condition. The stem is recessed at 2d so that the operable portion 17a is returned to its inoperative position when the needle is retracted. The rebated verge 15 may be tricked to guide the portion 17a and the verge may be made integral with or separate from the cylinder 3 and have bits 20 fixed therein. The needle retaining elements 17 are made of flattened piano wire. In a further modification (not shown) the needles may be deflected by wiping past a relatively stationary deflector cam. Alternatively the invention may be applied to the dial. The needle beds may be partly shogged before or after the deflection of the needles to place them in a better knitting position.
